What should come in place of ‘?’ in the given series?
17 30 43 56 69 ?
Correct Answer :
82
Solution :
The correct answer is 82.
To find the missing number in the given series, let us analyze the pattern or common difference between consecutive terms:
We can see that each number in the series is obtained by adding 13 to the preceding number (an arithmetic progression with a common difference of 13).
Therefore, to find the number that replaces the question mark (?), we add 13 to the last given number (69):
Hence, the missing number in the series is 82.
